If you have a wireless network then you are giving me your valid MAC addresses every time one of the valid clients sends or reecives traffic. Using MAC addresses to filter traffic on a wireless network just makes it harder for you to use your network. It has no effect on anyone who wants to get onto your network without your permission.
If you do not use wireless then I have several options depending on how much I want to use your IP address. If I were a casual user I would go to a neighbor with wireless. If I really wanted to use your IP address there are many ways to do so. Ask any college network admin how well they are able to enforce the one IP per dorm room drop policy. It is well known how to share an IP address provided by an ISP even without the help or knowledge of the owner of that IP address.
The judge was correct. The ISP can only prove that traffic was sent to an IP address. Unless you have a goverment/military secure channel from end to end there is no way to prove who received that traffic. It could be the owner of that IP address, anyone who stole it or a completely different IP address because the orginal IP address was modified before it arrived at the destination.
